Denmark, Sweden and Norway were ruled together under the Kalmar Union, established in 1397 and ending with Swedish secession in 1523.
Denmark and Norway remained under the same monarch until outside forces dissolved the union in 1814.
Denmark has the world's most flexible job market and one of the world's highest levels of education.
Combined with virtually non-existent corruption, this provides the recipe for a really good investment climate.
The architecture of Denmark has its origins in the Viking period, richly revealed by archaeological finds.
